Abstract: An electronic smoking article or electronic vaping article includes a reservoir containing a liquid material and having an outlet, a capillary having a capillary inlet and a capillary outlet, the capillary inlet of the capillary in communication with the outlet of the reservoir, a heater operable to heat the capillary to a temperature sufficient to at least initially volatilize liquid material contained within the capillary, and a shuttle valve between the outlet of the reservoir and the capillary inlet. The shuttle valve is operable to prevent release of liquid material from the reservoir when the shuttle valve is in a closed position and is operable to release liquid material from the reservoir when the shuttle valve is in an open position.

Abstract: An electronic smoking article includes a heater in communication with a liquid supply reservoir including liquid material and operable to heat the liquid material to a temperature sufficient to volatilize the liquid material contained therein and form an aerosol. The volatilized material flows through a sheath flow and aerosol promoter insert that is operable to cool the aerosol, reduce the particle size of the aerosol and increase the delivery rate of the aerosol.
